Water ring vacuum pump is a kind of black vacuum pump, and because it is simple in structure, the accuracy of manufacture is less demanding, easily processing, thereforeBe widely used gradually. But because water ring vacuum pump feature is that rate of air sucked in required is large when the low vacuum, in the time of high vacuum, rate of air sucked in required is little,Therefore, general water ring vacuum pump is applied to low vacuum field.
In order to utilize better water ring vacuum pump, expand its use field, those skilled in the art develop at former single pumpBasis on install the technical scheme of vacuum pump additional, make vacuum pump and water ring vacuum pump be combined into one and there is water ringVavuum pump its own advantages, the while can be applicable to need the vacuum extractor of high vacuum occasion.
Vacuum pump is mainly to use under high vacuum state, can increase flow velocity, improves rate of air sucked in required. Work as water ring vacuum pumpWhile being used in conjunction with vacuum pump, because the internal structure of vacuum pump is hourglass shape, in the time of low vacuum, rate of air sucked in required is large,Gas is subject to the impact of inner hourglass shape during by vacuum pump, causes the resistance that is subject to large, and flow reduces, thereby fallsThe efficiency of vacuum extractor in the time of low vacuum.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and taking out of application water ring vacuum pump that a kind of efficiency is high is providedVacuum plant.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions: it is a kind of that to apply taking out of water ring vacuum pump trueEmpty device, comprises main air inlet pipe, the first air intake branch, the second air intake branch and water ring vacuum pump; Dividing of described main air inlet pipeTong Guo the first air intake branch and the second air intake branch be communicated with the air inlet of water ring vacuum pump; On described the first air intake branch, establishHave vacuum pump, vacuum pump pilot gas flows to the air inlet of water ring vacuum pump.
In the time that the utility model moves, gas can flow to water ring vacuum pump from the first air intake branch and the second air intake branch simultaneously,In the time of low vacuum state, gas can flow to water ring vacuum pump through the second air intake branch in large quantities, has made up vacuum pump on groundThe little shortcoming of flow when vacuum state, therefore compared with prior art, the utlity model has and vacuumize the advantage that efficiency is high.
Preferably, described the second air intake branch is provided with the first valve, and described the first valve is optionally opened.
Preferably, described the first valve is vacuum valve.
Preferably, also comprise vacuum meter, described vacuum meter is used for being arranged on is taken out container.
In order to improve the seal degree of Water-ring vacuum pump steam inlet one end, below the first air intake branch and the second air intake branch adoptTwo kinds of modes connect:
The first: the end of described the first air intake branch is connected with the air inlet of described water ring vacuum pump; Described the second air inlet is propped upPipe end is connected with one end that the first air intake branch is connected with air inlet.
The second: the end of described the second air intake branch is connected with the air inlet of described water ring vacuum pump; Described the first air inlet is propped upPipe end is connected with one end that the second air intake branch is connected with air inlet.
In order to carry the seal degree being connected between main air inlet pipe and air inlet straight tube, the first air intake branch and the second air intake branch adoptTwo kinds of modes connect below:
The first: the head end of described the first air intake branch is connected with main air inlet pipe, the head end of described the second air intake branch and firstOne end that air intake branch is connected with main air inlet pipe is connected.
The second: the head end of described the second air intake branch is connected with main air inlet pipe, the head end of described the first air intake branch and secondOne end that air intake branch is connected with main air inlet pipe is connected.
Brief description of the drawings
The structural representation of the vacuum extractor of the application water ring vacuum pump that Fig. 1 provides for the utility model.
Detailed description of the invention
Below in conjunction with brief description of the drawings detailed description of the invention of the present utility model.
Referring to Fig. 1, a kind of vacuum extractor of applying water ring vacuum pump that the utility model provides, comprises main air inlet pipe 1,One air intake branch 2, the second air intake branch 3 and water ring vacuum pump 4; Described main air inlet pipe 1 respectively by the first air intake branch2 and second air intake branch 3 be communicated with the air inlet 401 of water ring vacuum pump 4; Described the first air intake branch 2 is provided with large gas blowoutEmitter 5, vacuum pump 5 pilot gas flow to the air inlet 401 of water ring vacuum pump 4. On described the second air intake branch 3, establishHave vacuum valve 301, described vacuum valve 301 is optionally opened.
Open at water ring vacuum pump 4 described in vacuum extractor initial start stage and vacuum pump 5, quilt is taken out container X, master enters simultaneouslyLevel of vacuum in tracheae 1 and each air intake branch is low, and described vacuum valve 301 is opened, and makes the first air intake branch 2 and secondAir intake branch 3 conductings simultaneously, guarantee the operational efficiency of vacuum extractor. After device operation certain hour, taken out container XIn level of vacuum lower, flow to vacuum pump 5 for gas is concentrated, the level of vacuum that makes to be taken out container X can be furtherImprove, now vacuum valve 401 is closed, gas is concentrated and is flowed to water ring vacuum pump 4 through the first air intake branch 2.
Observe the level of vacuum of being taken out container X for the ease of operating personnel, on container X, be provided with vacuum meter 6, operator being taken outMember can control according to the level of vacuum of being taken out container X the open and close of vacuum valve 401.
In the running of vacuum extractor, the air-tightness of pipeline has pass to the normal operation of installing and the effect vacuumizingThe impact of key, the quantity, the simplification pipeline interface organization that reduce pipe joint all help and the sealing journey that improves single unit system as far as possibleDegree.
